These might be the top best of all the games I ever played that might be enjoyable to play again years later. If there were other games in the series that were not mentioned that is because those games simply were not as good

Lands of Lore the throne of chaos

Dune 2 - The battle for Arrakis

The first Sonic the hedgehog for Sega Genesis

The Elder Scrolls - Daggerfall

Hyper Rogue

Ancient Domains of Mystery

The Seventh Guest

Wolfenstein 3D
